Option "DontZap" "boolean"
This disallows the use of the Ctrl+Alt+Backspace sequence. That
sequence is normally used to terminate the Xorg server. When
this option is enabled, that key sequence has no special meaning
and is passed to clients. Default: off.

Even if you kill CTRL+ALT+Backspace, they can still CTRL+ALT+F1, hit CTRL+C to kill startx, and have access to your live login shell.

This can also be disabled in xorg.conf

Code:

Option "DontVTSwitch" "boolean"
This disallows the use of the Ctrl+Alt+Fn sequence (where Fn
refers to one of the numbered function keys). That sequence is
normally used to switch to another "virtual terminal" on operat-
ing systems that have this feature. When this option is
enabled, that key sequence has no special meaning and is passed
to clients. Default: off.

Even better would be locking your workstation when you're not sitting in front of it, I've learned the hard way that you should always do this when other people can readily access your workstation ... You go to the toilet, and when you come back you discover that some stupid hack (coworker, friend of a coworker, kid, customer, whatever) closed all your windows, changed all kinds of settings, and who knows what else they did.

It's not even a matter of trust or security, just convenience and time-saving.

xlockmore can disable all CTRL+ALT key combinations.

Control-Alt-delete (to restart the system) is managed by the operating system. As for disabling it, the FAQs gave this answer, but I am not sure if it will work in X. You may have to lock C-A-D using X's keymapping too.
